Common with abstract nouns such as 'range', 'scope', 'gap', 'horizons', 'interests', 'understanding', and 'search'. Often used in semi-formal or formal contexts describing institutional changes or personal development. Distinguish from Sense 1 by the object type: Sense 1 takes concrete physical objects; Sense 2 takes abstract concepts.

常見錯誤

✅The company widened its product range.
💡'widen' needs a noun like 'range', 'selection', or 'variety'; it does not take the product names directly as an object.

✅The gap between rich and poor is widening.
💡'grow' or 'increase' are more natural with 'more'; 'widen' already expresses the change.
